I dont know if such a list exists - try extrapolating something you love.

Love fishing? What about using tidal information, public available fishing trawler data, weather patterns to suggest optimal fishing spots?

Love electronics? Can you index the top 10 global electronics companies and make a super slick product search with automatically updating pricing.

Love cooking? The BBC is shutting down their recipe website, mirror it, index it and make a cool search tool.

What do you love?
